This invention relates to an air conditioner particularly adapted foruse adjacent to or in connection with an air circulating tan.

It is aimed to provide an exceedingly simple 5 construction capable ofmanufacture and uplseep at low cost, which is portable so as to be movedfrom room to room or from building to building, which will occupyminimum space and which will be advantageous in the relief or asthma,

l hay-fever and the like. r

The more specific objects and advantages will become apparent from aconsideration of the description following taken in connection withaccompanying drawings illustrating an opera- 15 tive embodiment.

in said drawings:-

Figure 1 is a view in edge. elevation showing my improvements inconnection with an air cir culating fan;

so Figure 2 isa front elevation of the humidifier;

Figure 3 is a vertical sectional view talren on the plane of line t -dof Figure 2;

Figure 4 is a vertical sectional-view taken on the plane of line l -llof Figure 3;

25 Figure 5 is a fragmentary edge elevation oil the wheel frame andFigure 6 is a detail section taken on the line i l-t of Figure 1.

Referring specifically to the drawings wherein 30 like referencecharacters designate like or simi= lar parts, a suitable pan orreceptacle is provided at iii, adapted to contain water. A hood or archshaped wall it has its lower ends riveted or otherwise fastened as at itto opposite sides 3,, of the receptacle it). Wall ii is narrower thanthe receptacle and at the rear edge has a right angularly disposedflange or reinforcing plate it extending interiorly and eirterlorly ofthe wall it and also extending below the'top of the re- 40 ceptacle andin engagement with the sides or the latter as best shown in Figures 1and 2, so as to generally rigidity the structure.

A wheel or frame lie is rotatably mounted within the wall it and itextends into the. water 5 within receptacle iii. Such frame is'oi'skeleton form being made up of various wires it eittending outwardlyfrom connected hub plates ital, the radial rods it being connected bylateral rods it which may be parallel to the axis 50 of rotatiorrof thewheel but which are preferably at an angle to such axis of rotation asshown in Figure 5 at it", and inclining for wardly and downwardly.

A wick in the form of an elongated one piece -band or strip of cloth orother absorbent mate= 2, Mill, Serial No liritfitt (or. arreal rial ithas a hoolr ill at one end thereof adapted to detachably engage one ofthe rods it and then be wrapped over the remaining rods iii rotation oi"the wheel or frame, condition the air.

an arch shaped rod or bracket extends across the openings of the wallll, being journaled therein and held against displacement by a head amon one end of the bracket. Such bracket has a central spindle disposedwithin the space oi the wall it on which the wheel or frame isjournaled. Such wheel or frame has an abutment thereon engaged by one ofthe co hub plates that and at the opposite end has a nut 2i adjustablyscrew threaded thereon, between which and the other hub plate anerrpensive spring Eli and washers are mounted. Jlhe freedom of rotationof the wheel on the spindle 25 is controlled through the tension of thespring which is varied through the ad-' justment or the nut 2i.

At times it is preferred to have the wheel rotate on a horizontal axisand at other times it is preferred that the axis be inclined in order toincrease or decrease the effective action of a ran lib. it will also berealized that when the bars iii" are inclined as in Figure 5, more ofthe surface will be exposed to the blast from the fan lit i In order tofasten the wheel in different positions, one at an angle to thehorizontal, the bracket iii as best shown in Figures 1, 2 and 6 has anangular arm iii whose free end this 40 disposable selectively inopenings 33 and it in the wall it, according to whether the spindleshould be horizontal or inclined.

Preferably the wall it is reinforced by struclr= out ribs 7 v is litwill be realized that the device is portable and may be used inconnection with any fan of which that disclosed at iili isrepresentative, the same being a portable electric fan. The air from thefan impinges against the wiclr or other portions of the wheel, causingthe same to rotate through the water in the receptacle it, the wickabsorbing the same and due to the contact oi the air from the fantherewith, the air is ehiectively conditioned. The wheel rotates tiltusually rather slowly, the speed governed by the tension of the spring28.

Various changes may be resorted to provided they fall within the spiritand scope of the invention.
